It is considered the influence that sensible heat flux released in urban canopy layer causes to air temperature rise, using upper weather data observed at four towers that located between Osaka city and Higashi-Osaka city. Calculation methods for sensible heat flux and convection heat transfer coefficient from near surface to upper air are explained according to the heat budget model in surface boundary layer. Convection heat transfer coefficient, air temperature change with sensible heat flux change, and air temperature fall when heat island measure technology is introduced, are estimated with observation data at four towers. The difference by the year of convection heat transfer coefficient in surface boundary layer is almost ignored. The difference between daytime and nighttime of air temperature change with sensible heat flux change is around two or three times. This difference between towers is few.
